[0057] In one possible implementation, the configuration manner
includes the number of sequences being 2 or more; and the length of
the at least two sequences; where lengths of the at least two
sequences are the same or different.
[0058] Several alternative configuration manners are described
below in terms of exemplary embodiments.
Embodiment One
[0059] The number of sequences is 2, and the communication node
determines at least one of a frequency domain starting position of
each sequence, a frequency domain offset value of each sequence, or
a frequency domain spacing between different sequences.
[0060] A manner in which the communication node determines the at
least one of the frequency domain starting position of each
sequence, the frequency domain offset value of each sequence, or
the frequency domain spacing between different sequences may be
informing by control signaling, predefining a combination for a
communication node to select, pre-storing in a communication node
and triggering by control signaling, informing by a control
channel, or configuring by a higher layer.
[0061] The communication node may be a base station or a
terminal.
[0062] In an exemplary disclosure, the two sequences have the same
length and correspond to the same initial sequence; alternatively,
the two sequences may correspond to different sequences obtained by
different cyclic shifts of the same initial sequence; or, the two
sequences may correspond to different initial sequences;
alternatively, there may be a certain phase relationship between
the two sequences, or a certain phase relationship between multiple
elements within one sequence.
[0063] In an exemplary disclosure, the two sequences may be
composed in several manners: the two sequences are composed of the
same initial sequence; one sequence is a sequence obtained by
rotating the phase of each element of the other sequence by the
same angle (that is, rotating an overall phase of the sequence by a
certain angle); or, one sequence is a sequence obtained by rotating
the phase of each element of the other sequence by different
angles; or, one sequence is a sequence obtained by rotating the
phase of each element in the initial sequence by the same angle,
and the other sequence is a sequence obtained by rotating the phase
of each element in the initial sequence by different angles.
[0064] It should be noted that in the "rotating the phase of each
element by different angles", the phase rotation angle of each
element may have a certain phase relationship.
[0065] In an exemplary disclosure, the phase rotation angle has a
gradually rising trend; or, the phase rotation angle has a
gradually decreasing trend.
[0066] FIG. 2A is a schematic diagram showing an overall phase
rotation of pi/4 between sequence 1 and sequence 2.
[0067] FIG. 2B is a schematic diagram showing a phase rotation of
pi/4 of sequence 1 relative to an initial sequence and a certain
phase relationship between elements in sequence 2. In FIG. 2B,
there is a phase offset of pi/2 between each element in sequence
2.
[0068] FIG. 2C is a schematic diagram showing sequence 1 and
sequence 2 corresponding to different initial sequences, or
corresponding to sequences obtained by performing the cyclic shift
on different initial sequences. In FIG. 2C, there is no phase
relationship between the two sequences.
[0069] There are two sequences in each of FIG. 2A, FIG. 2B, and
FIG. 2C.
[0070] It should be noted that the two sequences described above
corresponding to the same initial sequence may represent that the
two sequences are generated by the same initial sequence. The
generation manner may include: being equivalent to the initial
sequence, rotating the phase of each element in the initial
sequence by the same angle, or rotating the phase of each element
in the initial sequence by different angles.
[0071] The two sequences described above corresponding to different
sequences obtained by performing the cyclic shift on the same
initial sequence may represent that the two sequences are generated
from different initial sequences, respectively, and these different
initial sequences described above are sequences obtained by
performing the cyclic shift on the same sequence, or these
different initial sequences are equivalent to the sequence. The
generation manner may include: being equivalent to the sequence,
rotating the phase of each element in the sequence by the same
angle, or rotating the phase of each element in the sequence by
different angles. In addition, the two sequences corresponding to
different initial sequences obtained by performing the cyclic shift
on the same sequence may also be referred to as the two sequences
consisting of the same sequence.
[0072] The above description is given by using an example of two
sequences. The meaning of multiple sequences corresponding to the
same initial sequence or multiple sequences corresponding to
different initial sequences obtained by performing the cyclic shift
on the same sequence is similar to the above meaning and not
repeated here.
[0073] The above description applies to other embodiments of the
present application.
[0074] In one possible implementation, the communication node
informs, through the control signaling, another communication node
of at least one of the frequency domain starting position of the
sequence, the frequency domain offset value of the sequence, or the
frequency domain spacing between different sequences.
[0075] The precision (or referred to as unit) of the frequency
domain starting position is one of H1 data subcarriers, 1/H1 data
subcarrier, H1 RACH subcarriers, 1/H1 RACH subcarrier, H1 RBs, or
1/H1 RB; where H1 is a positive integer, and / represents
division.
[0076] The precision (or referred to as unit) of the frequency
domain offset value is one of H2 data subcarriers, 1/H2 data
subcarrier, H2 RACH subcarriers, 1/H2 RACH subcarrier, H2 RBs, or
1/H2 RB; where H2 is a positive integer, and / represents
division.
[0077] The precision (or referred to as unit) of the frequency
domain spacing between different sequences is one of H3 data
subcarriers, 1/H3 data subcarrier, H3 RACH subcarriers, 1/H3 RACH
subcarrier, H3 RBs, or 1/H3 RB; where H3 is a positive integer, and
/ represents division.
[0078] In one configuration manner of the sequences, the frequency
domain starting position and the frequency domain offset value of
each sequence, or the frequency domain starting position and the
frequency domain offset value of one of the sequences and the
spacing between the two sequences may also be included except the
number of sequences, the length of the sequences, or the phase
rotation angle of each element in each sequence.
[0079] It should be noted that frequency domain offset values of
the two sequences may be the same or different. In the case where
the frequency domain offset values of the two sequences are
different, the configuration manner of the above sequences may
further include the frequency domain offset value of the other
sequence.
[0080] It should be noted that the spacing between the two
sequences may be a distance between starting point positions of the
two sequences; or a distance between final positions of the two
sequences; or a distance between one end of one sequence and the
other end of the other sequence. The spacing between the two
sequences may be determined by the communication node in the
following manners: informing by control signaling, predefining a
combination for a communication node to select, pre-storing in a
communication node and triggering by control signaling, informing
by a control channel, or configuring by a higher layer.
[0081] When the length of the sequences is 139, the corresponding
frequency domain offset value length may be one of {0, 1, 2, 3, 4,
5}. Two sequences with the length 139 may be mapped to both ends of
the entire frequency domain, and may correspond to different
frequency domain offset values, respectively, or the same frequency
domain offset value.
Embodiment Two
[0082] The number of sequences transmitted by the communication
node is S, corresponding lengths of the sequences are A1, A2, . . .
, and AS, respectively; corresponding frequency domain offset
values of the sequences are K1, K2, . . . , and KS, and the
sequences are correspondingly transmitted through a certain mapping
rule and in an equal spacing or unequal spacing manner, where S,
A1, A2, . . . , AS, K1, K2, . . . , and KS are nonnegative
integers, K1<=A1, K2<=A2, . . . , KS<=AS, where <=
represents less than or equal to. The number of corresponding
frequency domain offset values of the sequences is less than or
equal to S, and the number of the corresponding lengths of the
sequences is less than or equal to S.
[0083] A phase rotation of C exists between a phase rotation angle
of an element in each sequence and a phase rotation angle of an
element in the specified sequence, and the value range of C is 0 to
360.degree..
[0084] The communication node may be a base station or a
terminal.
[0085] X frequency domain units 1 are in the system, the spacing of
sequences is Y frequency domain units 2, the system includes Z
spacings, and the sequences are transmitted by occupying H
frequency domain starting positions; where H positions are
arbitrary.
[0086] X, Y, Z, and H are all positive integers, and H<=Z.
[0087] The H positions may be equally spaced, or occupied at both
ends, or occupied in the middle.
[0088] The H positions may be equally spaced so that the mapping of
the sequences in the frequency domain is consecutive.
[0089] The frequency domain unit 1 and the frequency domain unit 2
may each have the unit of one of K1 data subcarriers, 1/K1 data
subcarrier, K2 RACH subcarriers, 1/K2 RACH subcarrier, K3 RBs, or
1/K3 RB, where K1, K2 and K3 are positive integers, and /
represents division.
[0090] The system may contain 51 RBs at spacings of 5 RBs (the
spacing of each sequence starting point position), and the system
may contain 10 spacings (50 consecutive RBs).
[0091] In an exemplary disclosure, one sequence has the length of
12 and occupies 12 data subcarriers/REs (subcarriers and resource
elements (REs) are equivalent, 12 REs may be considered as one RB),
the number of transmitted sequences is 10, each sequence
corresponds to the same frequency domain offset value of 0 (less
than the length 12 of the sequence), the phase rotation angle of
the element in the sequence is 0, and over 10 transmittable
opportunities, RBs having any number of less than or equal to 10
RBs are occupied for mapping the sequences and transmitting the
sequences.
[0092] In an exemplary disclosure, the sequences are equally spaced
and there may be a certain cyclic shift or a phase rotation or
other variation among the sequences.
[0093] In an exemplary disclosure, the available RBs in the
frequency domain may be divided into 5 interlaces, where RB indexes
contained in the first interlace are a set of {1, 6, 11, 16, 21,
26, 31, 36, 41, 46}; RB indexes contained in the second interlace
are a set of {2, 7, 12, 17, 22, 27, 32, 37, 42, 47}; RB indexes
contained in the third interlace area set of {3, 8, 13, 18, 23, 28,
33, 38, 43, 48}; RB indexes contained in the fourth interlace are a
set of {4, 9, 14, 19, 24, 29, 34, 39, 44, 49}; and RB indexes
contained in the fifth interlace are a set of {5, 10, 15, 40, 25,
40, 35, 40, 45, 50}.
[0094] The above sequences may be mapped in all or part of RBs of
any interlace.
[0095] The above RB indexes may correspond to frequency domain
starting positions of 10 sequences.
[0096] In an exemplary disclosure, the RB indexes occupied by the
sequences are elements in the set of {1, 6, 11, 16, 21, 26, 31, 36,
41, 46}; or the set of {2, 7, 12, 17, 22, 27, 32, 37, 42, 47}; or
the set of {3, 8, 13, 18, 23, 28, 33, 38, 43, 48}; or the set of
{4, 9, 14, 19, 24, 29, 34, 39, 44, 49}; or the set of {5, 10, 15,
40, 25, 40, 35, 40, 45, 50}; or the set of {5, 50}; or the set of
{5, 15}; or the set of {4, 9}; or the set of {1, 41}; or the set of
{1, 45}. However, it is not limited to the above combinations. In
the embodiments of the present application, the above sequences may
be mapped to any combination of available RBs.
Embodiment Three
[0097] The number of sequences is more than one. A mapping manner
of the sequences in the frequency domain is determined through the
frequency domain starting position, the frequency domain offset
value and the frequency domain spacing (optional) between different
sequences included in the above configuration manner.
[0098] Due to the requirement of an occupied channel bandwidth
(OCB), the number of sequences is related to the subcarrier spacing
and the bandwidth.
[0099] In an exemplary disclosure, in the case where the bandwidth
is 20 MHz and the length of the sequences is 139, when the
subcarrier spacing is 30 KHz, the number x of sequences is
1<x<=4; when the subcarrier spacing is 15 KHz, the number x
of sequences is 1<x<=8; in the case where the bandwidth is 40
MHz and the length of each of the sequences is 139, when the
subcarrier spacing is 30 KHz, the number of sequences is
1<x<=8; when the subcarrier spacing is 15 KHz, the number x
of sequences is 1<x<=16; and in the case where the bandwidth
is 80 MHz and the length of each of the sequences is 139, when the
subcarrier spacing is 30 KHz, the number x of sequences is
1<x<=16; when the subcarrier spacing is 15 KHz, the number x
of sequences is 1<x<=32.
[0100] Where `<` represents less than; `<=` represents less
than or equal to.
[0101] The multiple sequences may have the same length and
correspond to the same initial sequence, or the multiple sequences
may correspond to different initial sequences obtained by
performing the cyclic shift on the same sequence.
[0102] The initial sequence is a sequence generated by a certain
rule, or a sequence obtained by performing a corresponding
operation on the generated sequence, or a predefined sequence.
[0103] It should be noted that the "corresponding operation" refers
to, but is not merely limited to, a cyclic shift, a phase rotation,
and the like.
[0104] In an exemplary disclosure, when the number of sequences is
4, the four sequences may correspond to 1, 2, 3, or 4 initial
sequences; when the number of sequences is 8, the 8 sequences may
correspond to 1, 2, 3, 4, 5, 6, 7, or 8 initial sequences; and
there may be a certain phase relationship among multiple sequences
to ensure that a cubic metric (CM) value is at a relatively low
level, but not limited to this.
[0105] In an exemplary disclosure, each sequence may be one of the
following: an initial sequence; a sequence obtained by rotating the
phase of each element in the initial sequence by the same angle
(that is, rotating an overall phase of the initial sequence by a
certain angle); or a sequence obtained by rotating the phase of
each element in the initial sequence by different angles.
[0106] It should be noted that in the "rotating the phase of each
element by different angles", the phase rotation angle of each
element may have a certain phase relationship.
[0107] In an exemplary disclosure, in the "rotating the phase of
each element by different angles", the phase rotation angle has a
gradually rising trend; or the phase rotation angle has a gradually
decreasing trend.
[0108] FIG. 3 is a schematic diagram showing an overall phase
rotation of pi/4 between sequence 1 and sequence 2 and an overall
phase rotation of pi/2 between sequence 2 and sequence 3. In FIG.
3, there are three sequences, and the three sequences correspond to
the same initial sequence or different initial sequences obtained
by performing the cyclic shift on the same sequence.
[0109] The communication node informs, through the control
signaling, another communication node of at least one of the
frequency domain starting position of the sequence, the frequency
domain offset value of the sequence, or the frequency domain
spacing between different sequences.
[0110] The precision (or referred to as unit) of the frequency
domain starting position is one of H1 data subcarriers, 1/H1 data
subcarrier, H1 random access channel (RACH) subcarriers, 1/H1 RACH
subcarrier, H1 RBs, or 1/H1 RB; where H1 is a positive integer, and
/ represents division.
[0111] The precision (or referred to as unit) of the frequency
domain offset value is one of H2 data subcarriers, 1/H2 data
subcarrier, H2 RACH subcarriers, 1/H2 RACH subcarrier, H2 RBs, or
1/H2 RB; where H2 is a positive integer, and / represents
division.
[0112] The precision (or referred to as a unit) of the frequency
domain spacing between different sequences is one of H3 data
subcarriers, 1/H3 data subcarrier, H3 RACH subcarriers, 1/H3 RACH
subcarrier, H3 RBs, or 1/H3 RB; where H3 is a positive integer, and
/ represents division.
[0113] In an exemplary disclosure, the sequences are mapped
consecutively in the frequency domain; or the sequences are mapped
at equal spacings in the frequency domain; or the sequences are
mapped at non-equally spacings in the frequency domain.
[0114] If the sequences are mapped consecutively in the frequency
domain, the configuration manner of the sequences may include the
frequency domain starting position of the first sequence without
frequency domain starting positions of subsequent sequences and the
frequency domain spacing between sequences.
[0115] In an exemplary disclosure, in one configuration manner of
the sequences, the frequency domain starting position and the
frequency domain offset value of the first sequence, and frequency
domain offset values of other sequences may also be included except
the at least one of the number of sequences, the length of the
sequences, or the phase rotation angle of the element in the
sequences.
[0116] If the sequences are mapped at equal spacings in the
frequency domain, the configuration manner of the sequences may
include the frequency domain starting position of the first
sequence and the frequency domain spacing between two adjacent
sequences. Alternatively, the configuration manner of the sequences
may further include the frequency domain starting position of each
sequence.
[0117] In an exemplary disclosure, in one configuration manner of
the sequences, the frequency domain starting position and the
frequency domain offset value of the first sequence, the frequency
domain spacing between sequences, and frequency domain offset
values of other sequences may also be included except at least one
of the number of sequences, the length of the sequences, or the
phase rotation angle of the element in the sequences.
[0118] If the sequences are mapped at unequal spacings in the
frequency domain, the configuration manner of the sequences may
include the frequency domain starting position of the first
sequence and the frequency domain spacings of other sequences
relative to the previous sequence. Herein, the previous sequence
may refer to a previous sequence, previous multiple, the first
sequence, or the like. Alternatively, the configuration manner of
the sequences may further include the frequency domain starting
position of each sequence. Alternatively, in the configuration
manner of the sequences, mapping positions of part of the sequences
are represented by the frequency domain starting positions, and
mapping positions of the other part of sequences are represented by
the frequency domain spacings relative to the previous
sequence.
[0119] In an exemplary disclosure, in one configuration manner of
the sequences, the frequency domain starting position and the
frequency domain offset value of the first sequence, a frequency
domain offset value of the second sequence and a frequency domain
spacing of the second sequence relative to the first sequence, a
frequency domain offset value of the third sequence and a frequency
domain spacing of the third sequence relative to the second
sequence, . . . , up to a frequency domain offset value of the last
sequence and the frequency domain spacing of the last sequence
relative to the previous sequence may also be included except at
least one of the number of sequences, the length of the sequences,
or the phase rotation angle of each element in each sequence.
[0120] It should be noted that the frequency domain offset value of
each sequence may be the same or different.
[0121] In an exemplary disclosure, when the length of one of the
sequences is 139, the corresponding frequency domain offset value
is one of {0, 1, 2, 3, 4, 5}.
[0122] It should be noted that the spacing between two sequences
may be a distance between starting point positions of the two
sequences; or a distance between final positions of the two
sequences; or a distance between one end of one sequence and the
other end of the other sequence. The spacing between the two
sequences may be determined by the communication node in the
following manners: informing by control signaling, or predefining a
combination for a communication node to select, or pre-storing in a
communication node.
Embodiment Four
[0123] The number of sequences is 1. The length of the sequence may
be any number less than a product of H4 and one of the number of
RACH subcarriers or the number of available data subcarriers, where
H4 is a positive integer, that is, the length of the sequence is
different from the length of the sequence in a set of {139, 839} in
the long term evolution (LTE) technology and new radio (NR)
technology. For example, the length of the sequence may be 12, 18,
24, 36, 283, 571, or 1151.
[0124] The communication node may select different sequence lengths
at different moments.
[0125] Multiple sequence lengths may be supported by the same
communication node.
[0126] The communication node may be multiplexed with data
information while transmitting a relatively long sequence.
[0127] The communication node may transmit sequences with the same
length or different lengths in different spatial directions at the
same moment.
[0128] The communication node may transmit sequences with the same
length or different lengths in different spatial directions at
different moments.
[0129] In one configuration manner of the sequence, the frequency
domain starting position and the frequency domain offset value of
the sequence may be included except the length of the sequence.
[0130] The above communication node may be a base station or a
terminal device.
[0131] In an exemplary disclosure, the sequence with a length of 12
may be mapped to one RB, the sequence with a length of 283 may be
mapped to 24 RBs, the sequence with a length of 571 may be mapped
to 48 RBs, and the sequence with a length of 1151 may be mapped to
96 RBs.
[0132] Accordingly, the sequence with the length of 12 takes the
frequency domain offset value of the following value: {0}.
[0133] The maximum value of the frequency domain offset value of
the sequence with the length of 283 may be: 24*12-283=5. Thus, the
value range of the frequency domain offset value of the sequence
with the length of 283 is: {0, 1, 2, 3, 4, 5}.
[0134] The maximum value of the frequency domain offset value of
the sequence with the length of 571 may be: 48.times.12-571=5.
Thus, the value range of the frequency domain offset value of the
sequence with the length of 571 is: {0, 1, 2, 3, 4, 5}.
[0135] The maximum value of the frequency domain offset value of
the sequence with the length of 1151 may be: 96.times.12-1151=1.
Thus, the value range of the frequency domain offset value of the
sequence with the length of 1151 is: {0, 1}.
[0136] In an exemplary disclosure, in the case where the bandwidth
is 20 MHz and the subcarrier spacing is 15 KHz, the length of the
sequence may be 1151, and the frequency domain offset value is one
of {0, 1}; in the case where the bandwidth is 20 MHz and the
subcarrier spacing is 30 KHz, the length of the sequence may be
571, and the frequency domain offset value is one of {0, 1, 2, 3,
4, 5}; and in the case where the bandwidth is 20 MHz and the
subcarrier spacing is 60 KHz, the length of the sequence may be
283, and the frequency domain offset value is one of {0, 1, 2, 3,
4, 5}.
[0137] The frequency domain offset value may be implicitly or
explicitly indicated to a communication node at the other side by
the communication node through control signaling.
[0138] The frequency domain offset value may also be determined by
the communication node itself.
[0139] It should be noted that the precision (or referred to as
unit) of the frequency domain starting position may be M1 data
subcarriers, N1 RACH subcarriers, or L1 RBs; where M1, N1 and L1
are positive integers; and the precision (or referred to as unit)
of the frequency domain offset value may be M2 data subcarriers, N2
RACH subcarriers, or L2 RBs; where M2, N2 and L2 are positive
integers.
Embodiment Five
[0140] The number of sequences is 2. The length of the sequences
may be any number less than a product of H4 and one of the number
of RACH subcarriers or the number of available data subcarriers,
where H4 is a positive integer, that is, the length of the
sequences is different from the length of the sequence in the set
of {139, 839} in the LTE technology and NR technology. For example,
the length of the sequences may be 6, 12, 18, 24, 139, 283, 571,
1151, or any number less than one of the number of available data
subcarriers or the number of RACH subcarriers in the system.
[0141] The lengths of the two sequences may be the same or
different. In the case where the lengths of the two sequences are
the same, mapping information (including the frequency domain
starting position, the frequency domain offset value, or the
frequency domain spacing between different sequences) in the
configuration manner of the sequences is consistent with that in
the embodiment one described above, which is not repeated here.
[0142] In an exemplary disclosure, in the case where the bandwidth
is 20 MHz and the subcarrier spacing is 15 kHz, when the number of
sequences is 2, the length of each of the sequences may be 571, and
the two sequences may be mapped consecutively or non-consecutively;
in the case where the bandwidth is 20 MHz and the subcarrier
spacing is 15 kHz, when the number of sequences is 4, the length of
each of the sequences may be 283, and the four sequences may be
consecutively mapped or non-consecutively mapped; and in the case
where the bandwidth is 20 MHz and the subcarrier spacing is 30 kHz,
when the number of sequences is 2, the length of each of the
sequences may be 283, and the two sequences may be consecutively
mapped or non-consecutively mapped.
[0143] FIG. 4 is a schematic diagram showing two sequences with
different lengths. As shown in FIG. 4, the two sequences correspond
to initial sequences with different lengths. Any of the two
sequences may be: an initial sequence; or a sequence obtained by
rotating the phase of each element in the initial sequence by the
same angle (that is, rotating an overall phase of the initial
sequence by a certain angle); or a sequence obtained by rotating
the phase of each element in the initial sequence by different
angles. There is no phase relationship between the two
sequences.
[0144] Alternatively, the length of one sequence may be 283 and the
length of the other sequence may be 571.
[0145] In one possible implementation, the communication node
informs, through the control signaling, a communication node at the
other side of the frequency domain starting position and the
frequency domain offset value of the sequence.
[0146] In an exemplary disclosure, the communication node informs,
through the control signaling, another communication node of at
least one of the frequency domain starting position of the
sequence, the frequency domain offset value, or the frequency
domain spacing between different sequences.
[0147] The precision (or referred to as unit) of the frequency
domain starting position is one of H1 data subcarriers, 1/H1 data
subcarrier, H1 random access channel (RACH) subcarriers, 1/H1 RACH
subcarrier, H1 RBs, or 1/H1 RB; where H1 is a positive integer, and
/ represents division.
[0148] The precision (or referred to as unit) of the frequency
domain offset value is one of H2 data subcarriers, 1/H2 data
subcarrier, H2 RACH subcarriers, 1/H2 RACH subcarrier, H2 RBs, or
1/H2 RB; where H2 is a positive integer, and / represents
division.
[0149] The precision (or referred to as unit) of the frequency
domain spacing between the different sequences is one of H3 data
subcarriers, 1/H3 data subcarrier, H3 RACH subcarriers, 1/H3 RACH
subcarrier, H3 RBs, or 1/H3 RB; where H3 is a positive integer, and
/ represents division.
[0150] In one configuration manner of the sequences, the frequency
domain starting position and the frequency domain offset value of
each sequence; or, the frequency domain starting position and the
frequency domain offset value of one of the sequences, and the
spacing between the two sequences may also be included except at
least one of the number of sequences, the length of the sequences,
or the phase rotation angle of each element in each sequence.
[0151] It should be noted that frequency domain offset values of
the two sequences may be the same or different. In the case where
the frequency domain offset values of the two sequences are
different, the configuration manner of the above sequences may
further include the frequency domain offset value of the other
sequence.
[0152] It should be noted that the spacing between the sequences
may be a distance between starting point positions of the
sequences; or a distance between final positions of the sequences;
or a distance between one end of one sequence and the other end of
the other sequence. The frequency domain spacing between the
sequences may be determined by the communication node in the
following manners: informing by the control signaling to a
communicate node at the other side, or predefining a combination
for the communication node at another side to select, pre-storing
in the communication node at another side, or determining by the
communication node itself.
[0153] Alternatively, when the length of the sequences is 283 or
571, the frequency domain offset value corresponding to each
sequence is one of {0, 1, 2, 3, 4, 5}.
Embodiment Six
[0154] The number of sequences is more than one. The length of the
sequences may be any number less than a product of H4 and one of
the number of RACH subcarriers or the number of available data
subcarriers, where H4 is a positive integer, that is, the length of
the sequence is different from the length of the sequence in the
set of {139, 839} in the LTE technology and NR technology. For
example, the length of the sequences may be 283, 571, or 1151.
[0155] Any of the sequences may be an initial sequence; or a
sequence obtained by rotating the phase of each element in the
initial sequence by the same angle (that is, rotating an overall
phase of the initial sequence by a certain angle); or a sequence
obtained by rotating the phase of each element in the initial
sequence by different angles.
[0156] The lengths of the multiple sequences may be the same or
different. In the case where the lengths of the multiple sequences
are the same, mapping information (such as, the frequency domain
starting position, the frequency domain offset value, or the
frequency domain spacing between different sequences) in the
configuration manner of the sequences is consistent with those in
embodiment one and embodiment three described above, which is not
repeated here.
[0157] FIG. 5 is a schematic diagram showing three sequences with
different lengths. As shown in FIG. 5, the three sequences
correspond to initial sequences with different lengths, and there
is no phase relationship among the sequences.
[0158] In an exemplary embodiment, when the number of sequences is
4, the lengths of the four sequences may be four cases including 1,
2, 3 and 4 lengths.
[0159] For example, in the case where there is one length for the
four sequences, the lengths of the four sequences are the same.
[0160] In the case where there are two lengths for the four
sequences, the lengths of two of the four sequences are both X, and
the lengths of the other two sequences are both Y; alternatively,
the lengths of three sequences are each X, and the length of the
other sequence is Y; where X is not equal to Y.
[0161] In the case where there are three lengths for the four
sequences, the lengths of two of the four sequences are both X, the
length of one of the four sequences is Y, and the length of the
last one sequence is Z; where X, Y and Z are different.
[0162] In the case where there are four lengths for the four
sequences, the lengths of the four sequences are different.
[0163] When the number of sequences is 8, lengths of the eight
sequences may be eight cases including 1, 2, 3, 4, 5, 6, 7 and 8
lengths.
Embodiment Seven
[0164] In this embodiment, multiple bits are adopted to identify
different configuration manners. According to the embodiments of
the present application, the communication node may inform a
communication node at the other side of all or part of contents in
the configuration manners described above by adopting the control
signaling.
[0165] In an exemplary embodiment, if a 2-bit identification
configuration manner is adopted, "00" represents that the number of
sequences used by a user equipment (UE) is 2, each sequence has the
length of 283, consecutive mapping is performed, and a pi/4 phase
rotation exists between the two sequences; "01" represents that the
number of sequences used by the UE is 1, and the sequence has the
length of 571; "10" represents that the number of sequences used by
the UE is 2, each sequence has the length of 139, non-consecutive
mapping is performed, and the frequency domain spacing is 25 RBs;
"11" represents that the number of sequences used by the UE is 4,
each sequence has the length of 283, the consecutive mapping is
performed, an overall phase rotation angle of each sequence
relative to the preamble sequence is: [0, pi/2, 0, pi/2], and the
corresponding angles are 0, 90.degree., 90.degree. and 0 in
sequence.
[0166] There may be different bit correspondences for different
system bandwidths.
[0167] It should be noted that the sequence described in the
present application may be a random access sequence, a transmission
sequence of an uplink/downlink reference signal, a sequence of a
discovery signal, a synchronization signal sequence, a transmission
sequence of an uplink control channel or a measurement signal, a
transmission sequence of a downlink control channel, other signal
transmissions, or the like.
Embodiment Eight
[0168] According to the embodiments of the present application,
different configuration combinations may be adopted to realize the
balance problem of the system performance and the control
information load.
[0169] Alternative embodiments for the precision of rotation of an
angle are as follows.
[0170] A new sequence is composed of two initial sequences, and an
overall phase relationship exists between the two sequences, so
that four points with relatively good phase values are provided,
that is, [0, 90.degree., 180.degree., 270.degree. ],
respectively.
[0171] Embodiments of the present application may be configured in
the following two manners.
[0172] A configuration manner one: `1` represents that a 0.degree.
phase relationship exists between the two sequences; and `0`
represents that a 180.degree. phase relationship exists between the
two sequences.
[0173] A configuration manner two: `00` represents that a 0.degree.
phase relationship exists between the two sequences; `01`
represents that a 90.degree. phase relationship exists between the
two sequences; `10` represents that a 180.degree. phase
relationship exists between the two sequences; and `11` represents
that a 270.degree. phase relationship exists between the two
sequences.
[0174] In the system configuration, the configuration manner one
may be selected for the case where the system has a low requirement
for the phase precision or the system load is relatively large or
other conditions; while the configuration manner two may be
selected for the case where the system has a high requirement for
the phase precision or the system load is relatively small or other
conditions.
[0175] An embodiment of the present application further provides a
signal transmission device, and FIG. 6 is a schematic structural
diagram of a signal transmission device according to an embodiment
of the present application, and the signal transmission device
includes a determination module 610, a generation module 620 and a
mapping and transmission module 630. The determination module 610
is configured to determine a configuration manner of sequences,
where the configuration manner includes at least one of the number
of the sequences, the length of the sequences, or a phase rotation
angle of an element in the sequences. The generation module 620 is
configured to generate the sequences according to the configuration
manner. The mapping and transmission module 630 is configured to
map the sequences to channel resources and transmit the mapped
sequences.
[0176] In one embodiment, the configuration further includes at
least one of a frequency domain starting position, a frequency
domain offset value, or a frequency domain spacing between
different sequences; the mapping and transmission module 630 is
configured to map the sequences to the channel resources according
to the at least one of the frequency domain starting position, the
frequency domain offset value, or the frequency domain spacing
between the different sequences.
[0177] It should be noted that the random access sequences are
different in length and may correspond to different mapping rules
or the same mapping rule (including the frequency domain starting
position, the frequency domain offset value, or the frequency
domain spacing between different random access sequences). For
multiple random access sequences, there may be a certain phase
relationship between random access sequences.
[0178] Functions of each module in each device of the embodiments
of the present application may be found in the corresponding
description in the above method embodiments and are not described
in detail herein.
